When You've Only Got One Chance... Use Rexade

“You’ve got to be able to do it in one pass, so it can be stand-alone or combined with other things so you can do one pass, because when you have years like this one, you just don’t have time for two!” stated Gary Onus, Landmark senior agronomist from Moree whose Rexade trial was so inundated with rain, that he could only assess it by helicopter. His trial used Rexade mixed with 5g metsulfuron, 500 mL Agritone LVE, 145 mL propiconazole and 0.25% BS1000. The end result? “I’d have no hesitation using Rexade.”

Rexade™ herbicide with Arylex™ active is the soon-to-be registered post-emergent cereal herbicide from Dow AgroSciences. A combination of Arylex (Paradigm™ herbicide) and pyroxsulam (Crusader™ herbicide) Rexade is a powerful combination that provides cross spectrum weed control. Registered to control brome grass, phalaris and wild oats, as well as providing suppression of annual ryegrass, barley grass and silver grass, and 24 broadleaf weeds, Rexade will be the product of choice for growers this season.

Rexade has excellent compatibility with a range of broadleaf herbicides. This allows one pass weed control in situations where there is a combination of grass and broadleaf weeds present, with no impact on grass weed control or crop safety. Wide broadleaf spectrum when used alone or in mixtures with other broadleaf herbicides to control brassica weeds including turnip weed and wild radish, volunteer legumes, milk thistle, deadnettle, fleabane (seedling), fumitory and climbing buckwheat (with Hotshot™).

“You have on-label compatibility with Hotshot and MCPA LVE, so you can do three-way mixes, all on label. That crop safety factor is important, because there are certain times when you just get rain or the weather isn’t right and spraying gets delayed whilst the crop is approaching GS31 so you’ve got to put all three together. Having the ability to do that with Group A resistance is a winner!” exclaimed Rob Long, consultant agronomist, B&W Rural, Moree. Rexade can be used in wheat (excluding durum varieties) and triticale. It has a wide application window, from GS13 through to GS31. Adding to its flexibility, Rexade dissipates quickly in the soil, irrespective of soil pH. Minimum re-cropping intervals are dependent primarily on moisture, and do not restrict winter cropping options. Grazing options are also possible with a grazing withholding period (WHP) of 4 weeks, which was found to be a critical factor for many areas with Paradigm.

Crusader users will be pleased to know that Rexade is an easy to store and pour granular (WDG) formulation. “My grower was happy with the mixing. His comment was that it was better than Crusader where you had that settling out in the drum. With the granular Rexade we didn’t have those issues. He was definitely happy” reported Matt Beddison, agronomist OptiCrop, Western Victoria. Rexade has been developed with Dow AgroSciences’ patented GoDRI™ RDT™ (rapid dispersion technology). GoDRI RDT provides several benefits, including rapid dispersion, even in cold water, minimal foaming, no sedimentation (no clogged nozzles) and, high active ingredient loading (low use rates). In addition, all of the co-formulants used in this technology have low toxicity and are environmentally friendly.

Daniel Andrews, agronomist, Rodwell’s, Echuca summed up his trial: “The grower said to me that next year he will use heaps of Rexade – he said where he applied Rexade he didn’t see any wild oats coming back through the crop and the broadleaves – it smoked the broadleaves, it did a good job. I didn’t see any crop effect and the farmer didn’t mention any issues with mixing or application. I was pretty happy with what it did.”
